Deciding the appropriate neurosurgical approach to a brainstem mass requires close interaction between radiologists & neurosurgeons Once an approach is decided, location of arteries & cranial nerves near the planned access point,white matter tract mapping & volumetric assessment of the tumor in relation to posterior fossa landmarks help increase the efficiency of surgery while minimizing adverse effects Advanced MR techniques allow diagnosis of focal brainstem gliomas, susceptible to surgical treatment, as well as attempt to predict tumor growth pattern and behavior Preoperative neuroimaging evaluation allows performing brainstem surgery with acceptable morbidity & mortality rates

-Cases: we reviewed 45 cases of brainstem gliomas and 1 cavernoma treated in our institution (24 surgically) -Preoperative imaging protocol: MRI (T2WI, FLAIR sequences, pre and post-gadolinium T1, DWI, MR-angiography; 20 cases also had MR-Spectroscopy and DTI) and MDCT (MPR and volumetric reconstructions) -Discussion & Conclusion: The aim of this exhibit is to describe our experience in a neuroimaging based approach selection by showing several examples of pre-surgical planning. Collaboration between surgeons and radiologists allows highly complex and risky approaches such as the Kawase triangle and the telovelar approach, with acceptable outcomes
